Following elements of HTML have height attribute −

<!DOCTYPE html> <html> <head> <title>HTML DOM Video height</title> <style> * { padding: 2px; margin:5px; } form { width:70%; margin: 0 auto; text-align: center; } input[type="button"] { border-radius: 10px; } </style> </head> <body> <form> <fieldset> <legend>HTML-DOM-Video-height</legend> <video id="wordPressIntro" width="320" height="50" controls><source src=" https://www.tutorialspoint.com/html5/foo.mp4" type="video/mp4"></video><br> <input type="button" onclick="getTrackDetails()" value="Video Not Visible"> <div id="divDisplay"></div> </fieldset> </form> <script> var divDisplay = document.getElementById("divDisplay"); var wordPressIntro = document.getElementById("wordPressIntro"); function getTrackDetails() { wordPressIntro.height += 50; divDisplay.textContent = 'Video height: '+wordPressIntro.height; } </script> </body> </html>
